FEROT is a specialized MSC.Fatigue module that analyzes the fatigue life of rotating structures using the S-N method.

In setting up a proper Wheels analysis, it is important to first have a sound understanding of the operation of MSC.Fatigue within the MSC.Patran environment or within MSC.Fatigue Pre & Post. It is suggested that you first read and understand Using MSC Fatigue (Ch. 2). Job setup for a spot weld analysis is very similar to job setup for other fatigue analysis types with only a few differences, as pointed out in this chapter.

Certain limitations or restraints exist in setting up a Wheels analysis. These are mainly the fact that the analysis MUST be set up within a preprocessor, and that results are surface resolved. These stresses can then be used to make fatigue life predictions on every surface node using a critical plane S-N (total life) method.
